Founding Design Engineer

Batch: 2023/2024/2025/2026. What you'll actually do: - Build and ship the interactions, animations, micro-interactions, and core rendering engine work that powers Cardboard. - Optimize memory usage when projects reference tens of gigs of source media through smart streaming, caching, and asset management across OPFS, Cache Storage, cache headers, and related browser primitives. - Work across core product features like the editor timeline, end-to-end microsites, micro-apps, and polished elements across our marketing and blog. - Build reusable components and push the quality bar for everything that touches the surface, while respecting the user's device constraints. - Experiment with new interaction patterns, shaders, and creative techniques. Ship the ones that make the product feel more alive. - Write great design.md files. Set interface guidelines for the team and our agents in the spirit of interfaces.rauno.me. Raise our accessibility standards. - Wire up API endpoints when the work demands it. - Solve these hard problems. Who you are: - You have deep knowledge of easing and timing. Ease-out, ease-in-out, linear: you know when and why. You have opinions about 80ms vs 300ms. - You're fluent in GSAP, Framer Motion, and Three.js. You're comfortable with shaders, dither effects, and SVG animation performance. - You're solid in WebGL and GLSL. You understand rendering pipelines from the inside, not just as an API. - You're obsessed with frontend performance. You can profile browser performance bottlenecks and systematically optimize them, especially during extended editing sessions. - Bonus: you're excited about WebGPU and where it's going.
